    tracker: Correctly escape strings on sparql updates
    
    When creating a sparql query, only the special characters need to be
    escaped. However, g_strescape replaces the non-ascii characters with a
    '\' followed by their octal representation. This results in a invalid
    query when a string contains non-ascii characters.
    
    Using tracker_sparql_escape_string function instead of g_strescape
    fixes this issue.
